The best way is first play the game trough. Enjoy the game and then pick them one by one.

1. You are awesome.
Really you are, we love you. Thanks for buying the game. 99,9 % have it. I dont know what the 0,1 % did? Self explaining. Should works fine, if you have problems with it, ask the developer :)

2. Intelligent Life Detected
Congratulations, you are not dumb. 84,9 % have it so 4 of 5. I think its for finishing the tutorial? Kill the first guy and let the 2nd alive or not and go to the end. Wow.

3. Big Spender
Spend some Magnificents at the store. 72,5 % still have it so nearly 3 of 4. Just go to the shop left down at the start of the level and buy a weapon or an cheap upgrade for your pistol, its wayne you need to buy all upgrades of all weapons later and its very helpful only take some time for the other 3 achievements i come later.

4.Tottally not racism.
Seriousy, we hate racism. 50,1 % so 1 of 2 players get it. Its for killing a black warden in level 1, not the white cops. Very easy if he dont kills you first :)

5.Guns don´t kill people I
Agent Awesome kills people. 34,1 % (1 of 3 get it) I hope it is for killing 10 Wardens or kill a special guy (i am not 100 % sure). Should be done at level 2-3 if you kill every time all and get the Genocide Bonus (what i would prefer to start with) first play like rambo and later like sam fisher/ solid snake ;)

6.Seriously?
You just shot a dog dude, what´s wrong with you? 25, 3 % (1 of 4) in level 2 or 3 should be the first dog, take your pistol and kill him.

7. Guns don´t kill people II
And dogs, and aliens. 25 % (1 of 4) (now you need to kill after the dog an alien or killing 25 People, just kill everyone and everything in your first 12 levels walktrough and get all levels genoicde + destroying robots and you should get this one too very fast.

8. No more TPS Reports
Complete "The Office" section of the game 23 % (1 of 4-5) Should you get after you finish level 4 (Tutorial is level 0)

9. I F**king hate science.
That guy was researching a cure for Ebola ♥♥♥♥♥♥♥. 20,6 % (1 of 5) In level 5 or 6 should be a scientist with white hair, kill one and hope that it pop up. I am not 100 % for sure i just hope it, if not send me a message and i ask the developer :D

10. PETA will be mad
Koalas cuteness levels drop to zero when they try and kill you 20,3% (1 of 5) Again just kill one of the blue koalas, you cant miss their are many between level 5-8 to kill.

11. Guns don´t kill people III
And cyborgs and sharks. 15 % so now kill cyborgs and the sharks or maybe kill 50 Wardens, i am not sure (sharks you cant oversee and are many in the later levels but which unit is the cybord i have forget, but if you kill all with genoicide bonus) that should be 0 % a problem.

12. A god amongst men
Whoa, that was amazing. You should Youtube that ♥♥♥♥. 12,8 % (1 of 9 players) (I think for this you should get at the end of the Level the Rang Agent God. I dont know which levels you can get it. But its not so hard. If you get ghandi ghost (dont kill any warden and dont let you see), favorismn (use only one weapon), tough guy (dont get hurt), nade using only (at the end target) and master strategyst (using tactical view only 1 time at start) you should get it fast and quick :) if there are problems ask me i maybe could make a video :)

13. Poor
Earn a total of 10,000 Magnificents 12,3 % (1 of 9). That are only a few. On highest level with 2 runs on master strategy you could do it, but i show you how to farm quick on a low level later on the higher type of this collector item.

14. Maxed Out
Max any stat of any weapon. 12 % (1 of 9) Get all updates of ONE (Ammo, Range, ...) of the buy options for the pistol or any other weapon and you should get it. Only a thing of time and Magnificents.

15. Research & Death
Complete "The Lab" section of the game 11,5 % (1 of 9) just finish level 5,6,7,8 and voila :)

16. Proved your awesomness
Finish the game. 11,5 % (1 of 9) just finish level 9,10,11,12 if you have problems. Write me, getting better weapons could help but are not needable only full thug mask could be helpful for level 10 and 12 ghandi ghost and master strategy.

17. Guns don´t kill people IV
Basically Agent Awesome kills everything. 11,3 % (1 of 9) So kill every unit type or kill 100 wardens in the game.

18. Japanese Heritage

27. OP
Finish Level 1 Using only the RPG (use only the rocketluncher on level 1 ) 8,3 % kill them or kill only the target (maybe best you only choice the RPG and deleate the gun, but if you only use it, its a 1 min achievement.

28. Bacon Madness

Call me then i make a video

34. Circus Act

49. You should try sports
Because apparently videogames are not your thing (let attack an enemy another enemy with hack grenade)

So i forget now one, i oversee. Normaly 40 of 50 Achievements are really easy, 5-8 maybe a bit middle and only 2-5 hard and all 50 possible to do for everyone but thank the SAM user you must be happy with 40 of 50 till the developer has the money to fix them. We only can hope, but we need not to invest money for steam achievement bug fixing, trading cards and bug fixing to finish this game, the developer invest all his money in it, now we need to invest it to complete it. I hope you enjoy some hours. Its not the best strategy game, but it can make some hours qualify fun if you like the highest challenges do yourself with lowest possible equipment. Thank you and have a nice day.
